Bristol Palin is thrilled to have been reunited with her two daughters after two weeks apart.

The mother, 27, took to Instagram on Tuesday to share a photo of her three children — nine-year-old Tripp, her son with ex Levi Johnston, 28, as well as Sailor, two, and Atlee, one, her two daughters with Dakota Meyer, 30.

Tripp can be seen reading to his sisters as all three siblings are gathered on the same bed, with the big brother holding up a book while Atlee and Sailor listen.

'Just melting my heart,' Bristol wrote next to the image, in which Sailor and Atlee can be seen, dressed in matching pajamas, snuggling close to their brother, who is wearing all in neon green.

Bristol's daughters have just returned to their mother's home after spending two weeks with Dakota, Bristol's ex-husband, in Kentucky.

The former Marine shared several photos taken during their stay on his Instagram account, writing in the caption: 'We had a great time in KY the last two weeks.

'I've always heard you are the average of the people you surround yourself with. Well every time I come back I realize just how incredible the people around me are and when I look at them I can only hope to one day be the average of that. A great life starts with a great foundation.'

While Sailor and Atlee were with Dakota, Bristol made no secret of how much she missed her two daughters. She shared a photo of herself with her youngest, asking in the caption: 'How can you speed up time when your babies are with the other parent?'

On another occasion, Bristol shared a couple of photos of her daughters on her Instagram Story and said that she was missing them 'so much it hurts'.

Bristol and Dakota, who divorced earlier this year, have sparred publicly about their breakup in the past few weeks. The couple are currently featured on MTV's Teen Mom OG, which started filming before their split — and therefore documents the end of their marriage.

On Monday's episode, Dakota said he felt like 'someone would feel if they got out of a life sentence prison', referring to his and Bristol's decision to break up.

Last week, Bristol hit back at Dakota's claims that she kept him away from their daughter Sailor around the time of her birth, saying his allegations were 'absolutely not true' in an explosive response.

Dakota had said on Instagram that a pregnant Bristol had left him just a week before their first planned wedding and that he wasn't 'invited' to the birth of Sailor, now two.

Bristol and Dakota were first set to tie the knot in May 2015 in Dakota's home state of Kentucky, but that wedding was called off. They had their daughter Sailor in December 2015 and married in June 2016 in a surprise ceremony.

Dakota had also claimed that he found out about Sailor's birth on Twitter, which is among the claims Bristol vehemently denied while speaking to Radar Online.

'I turn my other cheek on a lot of things, and I will continue to do so because my children deserve parents who respect each other,' she told the website.

'But for Dakota Meyer to say that he found out about the birth of our daughter from Twitter is absolutely not true.

'I will not stand by and allow false evil information, such as this, to be printed for our daughter to see one day.'

Bristol said that Dakota was the one who asked her not to contact him after they breakup, adding that she did get in touch with him at the time of her 12-week ultrasound to tell him the baby was likely a girl and let him know the due date.

'I did not hear from him again until a couple of days before my due date when I received a letter stating that he had the tools and expected to be a custodial parent,' she added.

Bristol said that contrary to Dakota's claims, he was fully aware of Sailor's birth because he and Bristol's father, Todd Palin, 54, had kept in touch, and Todd told Dakota Bristol was in labor.

'I sent Dakota a picture of our newborn baby girl right after she was born, and did not get a response. My father also sent him a picture of Sailor Grace,' Bristol added.

The mother said she realized 'the second' Sailor was born that she had made a 'completely unnecessary mistake' when she told Dakota to prove his paternity, and that she was heartbroken that her daughter did not have a father present at her side.

But she added that Dakota 'unfortunately continued down the legal route of establishing paternity', and that the former Marine 'refused' to meet Sailor until he had legal visitation rights.

She expressed the hope that she and Dakota can mend their relationship and that they will find themselves in a 'better place' soon, referring to her ex as an 'outstanding father'.

In his Instagram post, Dakota had offered more details about the events that led to the cancellation of the pair's first wedding and its aftermath. The couple had gotten engaged during a Rascal Flatts concert in Las Vegas in early 2015.

Dakota began his post, which featured a photo of him holding Sailor in his arms, by saying Bristol 'got pregnant right after [their] engagement'.

'We planned a wedding with our families and friends and Bristol decided to leave me a week prior,' he added. 'I spoke with her family every month and made it clear I would be the father of my child.

'I reached out to her before Sailor was born and asked what the plan was to co-parent. She told me to go through the courts to establish paternity.'

Dakota opened up about the circumstances of Sailor's birth, adding: 'I wasn't invited to the birth and found out my child was born on Twitter — can you imagine being a dad and not being allowed to be at your child's birth?'

He added about Bristol: 'She denied my paternity until it could be proven, at which point Sailor was born. For Bristol to state that Sailor didn't have a dad is laughable — what really happened is Bristol kept our daughter from having a father present at birth and until the courts ruled that I was her father.

'I can promise you this, Sailor and Atlee always had a dad, and always will have a dad.'

Back when Bristol announced her pregnancy, a month after her and Dakota's canceled wedding, she initially didn't disclose whether the former Marine was the father of her child.

Bristol Palin and Dakota Meyer's relationship: a timeline

Bristol and Dakota met in 2014 during the filming of Sarah Palin's Sportsman Channel show Amazing America.

They planned a wedding in Dakota's home state of Kentucky, which was called off at the last minute in May 2015.

Bristol and Dakota's first daughter together, Sailor, now two, was born in December 2015.

In early 2016, it was revealed that Dakota was being asked to take a paternity test as part of a bitter battle over custody of Sailor.

Dakota and Bristol tied the knot in June 2016.

In December of that year, Bristol, who also has a nine-year-old son called Tripp with her ex Levi Johnston, 28, announced she was expecting her third child — her second with Dakota.

She gave birth to their daughter Atlee, now one, in May 2017.

It emerged in February this year that Dakota had filed for divorce.

Bristol confirmed in August that the proceedings had been finalized.

In January 2016, DailyMail.com revealed exclusively that Dakota was being forced to take a paternity test in an increasingly bitter battle over custody of Sailor.

Dakota also took to Instagram Stories to answer questions from his viewers regarding his relationship with Bristol and their split.

He said he did file for divorce from his wife, saying he only did so after she told him she wanted a divorce and had 'already met with an attorney first'.

Dakota acknowledged his PTSD and anxiety, which Bristol has cited as important factors in their split, adding: 'but I wasn't married to anyone perfect'.

When one Instagram user asked Dakota when he knew enough was enough, he replied: 'I knew enough was enough when I would hear her talk to her family in front of me and say "I can't believe I wasted three years with a mother f***er like this."'

Another person asked Dakota whether he ever feared he might hurt someone while having a PTSD episode, to which he said: 'That's such a great question. No, absolutely not. I've never put my hands on Bristol. I've never hurt Bristol. I've never said anything to Bristol she hasn't said to me, so let's clarify that.'

The father also revealed that he has a 'week on, week off' custody arrangement with Bristol and admitted that he does have a nanny, adding 'but I also have a job hahaha'.
